3.1.6 Expansion Connectors (J8 to J12)

The M3A-HS37 is provided with through-holes for expansion connectors. The SH7137 I/O pins are connected to the
through-holes.
MIL-spec connectors can be connected to the through-holes (J8 to J12), allowing for connecting with expansion boards or
monitoring the SH7137 bus signals. Figure 3.1.7 shows the pin assignments for expansionsion connectors.
